[Twisted-Python] Nested/Aggregate Exceptions
by Justin Mazzola Paluska March 29, 2006

March 29, 2006

Hello, I'm writing a Twisted application using Twisted 2.0.1 on Mandriva 2006 that uses PerspectiveBroker for communication between modules. Our application is based on a centralized Twisted server and web- and GTK-based client applications that connect to the Twisted server to manage a user database. Up until recently, most of methods exported by the Twisted server are essentially single-operation functions that operate on a single user (e.g., "update_user(user, **data)"). As such, … [View More]

[Twisted-Python] Twisted Sponsors

March 29, 2006

So I'm compiling a web page listing everyone who has donated money, hardware, software, hosting, etc to Twisted. You can see the work-in-progress here: http://twistedmatrix.com/trac/wiki/TwistedSponsors As part of maintaining win32 I would like a place to thank people for all the stuff I am about to ask for ;) I'm probably leaving out a lot of people, so would whoever is in the know please response, and we can get a comprehensive list sorted out. -Eric

> - zsh_extras = [":file to read from:action", ":file to write > to:action"] > + zsh_extras = [\":file to read from:action\", \":file to write > to:action\"] Why were changes like that made? Isn't it a no-op, since they were in triple-quoted strings anyhow? It would be nice if the docs were actually usable/readable by people viewing the source as well as people viewing the generated docs, where possible. James

Re: [Twisted-Python] Degrading under load
by Yitzchak Gale March 26, 2006

March 26, 2006

Sorry, I guess my question wasn't clear enough. The most important things I need to know are: When running listenTCP, how often does twisted accept pending connections on the port? Is it only when the previous connection is finished processing, or every time the event loop gets control, or something in between? And when twisted does accept pending connections, does it accept ALL of them and queue them all for processing, or just one at a time? Thanks, Yitz My original post: > I need to … [View More]

[Twisted-Python] Getting splitted data with SSHChannel.dataReceived
by Mustafa Sakalsiz March 26, 2006

March 26, 2006

Hi, I am using twisted conch to execute a remote program (say ProgA) through ssh. In ProgA, I print some datas and catch them in the dataReceived method of SSHChannel. Sometimes, the data comes partially, like this ProgA dataReceived ------------ -------------------------------- prints TWISTED gets TWISTED and appends it to TOTAL . . . prints TWISTED if len(TOTAL) is 1020 gets TWIS (gets … [View More]

[Twisted-Python] Motivations of Twisted Developers & $200 Docstring Challenge

I'd rather not, and I'm sure you'd rather have me as a user, but that's just the way it is. I'm an active user of Twisted, but even after several years, I'm still not sure whether the Twisted developers really *want* you as a user or not. I'm not saying that with any hostility; I'm actually a big fan of Twisted and those behind it. They certainly have been very helpful to me with my specific questions on IRC, and in that way it's one of the most responsive and "live" F/OSS projects around. Frankly, I think the Twisted developers understand Python and the theoretical underpinnings of software engineering better than 90% of the people developing with Python today. On the other hand, though, much of the style of development that goes on almost seems *intended* to turn off potential users, such as abandoning subprojects mid-stream in favor of a Next Big Thing that remains a moving and largely undocumented target for long periods of time, and failing, for reasons incomprehensible to me, to simply write even 2-3 lines explanations of what their New and Improved code is actually *doing* in the docstrings that Python so conveniently provides for that purpose. Ironically, one of the latest examples of this is a document extractor under development that is supposed to fix some alledgedly grevious flaws in epydoc (undetected by this user, by the way) that actually has very little source material to work with from the Twisted code itself! Another most unfortunate example is that the most powerful way to do networking with Python is without a recommendable HTTP server. The Twisted devs won't recommend twisted.web because it is "hopelessly broken" yet they have nothing released to support it. Twisted web2 remains largely undocumented and the developers advised those using it to do so at their own peril. Note to developers: serving HTTP is the biggest single use-case for Python networking! I've complained about these issues for a long time. Now I'm going to put my money where my mouth is. I hereby commit to a two hundred dollar ($200) payment to Twisted, c/o the exarkun(a)divmod.com account listed under the "Contributing" heading of http://twistedmatrix.com/trac/, in exchange for one or more of the Twisted developers committing SVN/trunk changes in the next two weeks that implement at least 100 meaningful class or method docstrings in new or active portions of the Twisted API. (I'd personally appreciate a focus on twisted.web2 as that's what I'm spending my time on right now, but this challenge is open to any active parts of the API.) That works out to $2 per docstring, and those "in the know" should be able to write them in just minutes apiece. Spend five hours writing all of them (improving "your" parts of Twisted in the process) at 20 docstrings per hour and pocket $40/hr for your efforts. It sounds like a pretty good deal to me, and hopefully to the Twisted devs as well. If this challenge is accepted and it works out well, I might even do it again -- I'm *that* interested in the ultimate success of this sometimes wonderfully crazy library/framework/Integratotron* Let me know. Best regards, Ed Suominen * See Glyph's somewhat amusing and thought-provoking blog entry of March 15: http://glyf.livejournal.com/54500.html [View Less]

[Twisted-Python] on avoiding our policy: casual fixes branch
by glyph＠divmod.com March 24, 2006

March 24, 2006

Right now, there are no exceptions to the rule of "make sure there's a ticket before you check any code in to trunk". However, several people raised some concerns on IRC over the additional friction this adds for minor fixes (the change in question being spiv's doc correction of "the the"). It's worth noting that if branching is difficult for you, it is also perfectly acceptable to attach a patch to a ticket. The important thing is that a ticket exist first, so that merging and reviewing can … [View More]
